Medicare special needs plans tied to fewer end-of-life hospitalizations in dementia

Clinical takeaway: Special needs plans may reduce aggressive end-of-life interventions for nursing home dementia patients, with benefits building over the first few years a plan operates in a facility.

Nursing home residents with dementia are often hospitalized in their final weeks, despite frequently being treatable in place. Institutional Special Needs Plans (I-SNPs), a type of Medicare Advantage plan for long-stay residents, embed advanced practice clinicians in facilities to manage acute illness and lead advance care planning.

The model has grown and diversified over two decades, but most evidence still comes from the oldest and largest version run by UnitedHealthcare (UHC). This study examined whether enrollment was linked to different end-of-life care, and whether newer non-UHC plans, which have driven recent growth, performed as well.

After accounting for the healthier patients these plans tend to enroll, UHC enrollment was associated with a 9-percentage-point drop in hospitalization in the last 30 days of life, against a baseline rate of 28%. Non-UHC enrollment showed a smaller 5.9-point reduction. ICU admission and mechanical ventilation moved the same way, with larger effects under UHC plans.

Hospice use, by contrast, showed no association with enrollment, in either plan type. The authors suggest I-SNP clinicians may already be managing palliative needs in place, though they note the relationship needs more study.

The benefit also depended on how long a plan had operated in a facility. Reductions in hospitalization grew over roughly the first three years after a nursing home adopted an I-SNP, then plateaued, consistent with the time it takes to build clinical capacity and enroll enough residents to support a regular on-site clinician.

The study drew on 2010 to 2022 Medicare data covering 1.4 million long-stay residents with dementia who died between 2013 and 2022.

"I-SNP enrollment was associated with significantly fewer hospitalizations for nursing home residents with dementia at the end of life, with effect sizes larger for UHC vs non-UHC I-SNPs. Plan maturity and volume are likely important factors impacting success. " the authors concluded.
